rock wool board

Rock Wool Board Introduction Rock wool board is a well - known insulation material widely used in various fields. It is mainly made from basalt, a natural volcanic rock. Through a series of processes such as high - temperature melting, fiber - forming, adding binders and other additives, and finally solidifying and cutting, rock wool board is produced. Basic Parameters - Thermal Conductivity: Usually ranging from 0.036 - 0.048 W/(m·K). This indicates its excellent thermal insulation performance. Heat transfer through rock wool board is slow, effectively preventing heat exchange between the inside and outside of a building. - Density: Generally between 80 - 200 kg/m³. The density affects the strength and insulation performance of the rock wool board. A low - density rock wool board is relatively light but has relatively low strength; a high - density one has high strength but a relatively high cost. - Fire - Resistance Performance: Rock wool board is a Class A non - combustible material. In case of a fire, it will not burn and will not produce toxic or harmful gases, effectively preventing the spread of fire and buying time for people to evacuate and for fire - fighting rescue. - Moisture Absorption Rate: Usually no more than 5%. The low moisture absorption rate enables it to maintain good insulation performance even in a humid environment without being affected by moisture. Description Rock wool board has a fibrous structure. It is soft to the touch, yet it has good integrity. It can be cut into different shapes and sizes according to actual needs. Due to its excellent properties, it is not only used for building insulation, but also for sound - absorption, vibration - reduction and other applications in industrial and other settings, providing a comfortable and safe environment.
